Re: Instruction on how to convert lossless .wma to .flac

A method using ffmpeg was described earlier in this thread.
The package ffmpeg is no longer available from the Mint 17 repositories.
You have to install the package libav-tools and then use the command "avconv" in place of "ffmpeg"
The parameters used with avconv seem to be the same as those used with ffmpeg.
Code: Select all
avconv -i someFile.flv -t actualLength -ss startDelay -vn -acodec copy outFile.m4a

This will extract a .m4a (aac codec) music file from a downloaded Youtube flash video file with the same sound quality as in the original file.
"startDelay" is the time in seconds after the video begins before the audio actually starts.
"actualLength" is the final required length of the .m4a file in seconds.
i.e. these 2 values allow cropping off the start and end of original file.

Due to some annoying limitations of various apps, I've gotten into the habit of using the 'chains' feature of Audacity.

- Add a new simple chain procedure using File/Edit Chains, call it say 'wma2flac'.
- Insert two steps in this order: Normalize and ExportFLAC. Click OK to save the chain. Note - the Import command is not yet working, not sure why.
- Delete and/or save any open audio files.
- Run File/Apply Chain, select 'wma2flac', select files to convert, click Open and watch the conversions.

Job done!
